This paper presents a method for shapes modeling of 3-D objects using a B-spline surface model based on a projection expression. The surface model is ...
The paper describes a method for generating a generic deformable model from a training set of shapes depicted in a corpus of image sequences.

We propose algorithms to set the cross-derivatives of multi-sided patches defined by Bézier and B-spline ribbons. Boundaries and surface constraints are ...
The general technique is to apply a base surface and to modify this surface, via constrained shaping, to achieve interpolation or approximation to a given ...
A method is presented for approximating surfaces, which are the solutions of partial differential equations, in terms of B-splines so that they can be ...
With 3D scanning, modeling systems can import organic or sculp- tured shapes that would otherwise be difficult to create. For instance, in the automobile ...
